D Handicap and equality in wagering shogi

Abstract

In shogi, there is an official handicap called ”komaochi” that has been established since the Edo period. In the late Showa period, shogi gamblers began to specialize in shogi gambling, and shogi began to be used as a form of gambling, which led to the creation of a handicap unique to wagered shogi. This paper summarizes the historical background, compares the official handicap komaochi with the handicap in wagered shogi, and clarifies the differences in the perception of equality expressed by each handicap.
